Circuit for and method of receiving a signal in an integrated circuit device

Abstract:

A circuit for receiving a signal in an integrated circuit is described. The circuit comprises a sampler configured to receive an input data signal, wherein the sampler generates sampled data and a recovered clock; a clock and data recovery circuit configured to receive the sampled data and the recovered clock and to generate a phase interpolator code; and a phase interpolator configured to receive the phase interpolator code; wherein the phase interpolator generates multiple phase interpolator control signals during a clock cycle based upon the phase interpolator code generated for the clock cycle.
